I Application une 10, 1931. Serial 543,370

18 Claims. (Cl. 12870) My present invention relates to a body treating table oi the type illustrated in my patent application 515,564 filed April 13, 1931.

A particular object and feature of the present invention is to reciprocate the table part of the structure on which the patient lies while the arm to which the feet, arms, or head, are connected, is oscillated, the object being to obtain an oscillating movement of the lower-or upper extremities of the body, this giving a bending actionquite frequently employed in osteopathic and chiropractic treatments.

In my present invention the supporting table or bed on which the patient rests is reciprocated in synchronism with the oscillating movement of the arm so that if the feet or arms are connected to the arm that undue strainswill not be exerted on the body but the patient mayrest comfortably and substantially only experience the movement caused by the oscillating arm. The reciprocation of the table or bed is arranged so that when the arm is in its lowermost-position the bed is. advanced toward the arm and when,

the arm is elevated the, bed is retracted. 1- A further detail object and featurejof myin- .vention is'varyingthe reciprocating movement of the bed in. accordance with a circular 'oscilla-. tion of the, armed that for theslight oscillation thebed will only have a slight reciprocating 3O oscillation the reciprocation of ,the table will be being. combined so that there isrsubstantially a constant distance from the body-clamp on; the

In this construction a driving mechanism 12 is of the same type as in my former patent application and operates the .arm 13 which has a universallyjointed connection 14 with a screw 15 mounted on theframe 16 which frame is se- 5 e cured to the drive shaft 17. The arm 13 is -piv ,oted by a pivot pin 18 in the rock shaft 1 9 and the universally jointed end lqi swingsin a circle it rocks the rock shaitl). The frame-16 and the screw 15 are the same as in my copends5 ing application Serial No. 515,564.

An arm 20, preferably formed tubular, is pivoted on'pivot 18 to the rock shaft 19 and is firmly connected to the end 21 of the arm .13

these both having a circular oscillation. The horizontal 'rock shaft 19 has pivot axles 19 .at each end, each axle beingpivoted in a lug so at opposite sides of the opening (note Figure 3). This forms a horizontal hinge or pivot for the rock shaft 19,.andthe pin1 8 extending therethrough may be'considered as a yertical pivot. As-the arm 20 is rigidly-connected to the arm 13, and this latterpivoted 3; on the vertical pivot bolt 19, hence as the arm 13 is given an orbital movement having hori- Zontal and vertical components, it communicates an orbital movement to the arm 20. I I

In my; present application the arm --2O is not 35 rock shaft 19, this plate being-substantially of the same type .as illustrated in my former patent application. A tension bracket designated generally at 25, isv secured to the outer portion of the arm 20, this being slidable; and is of substantially the sameconstruction and function as .95

in my former patent application.

' A reciprocating bed 26 employs longitudinal tracks 27 on the bottom, these tracks bearing and operating on rollers 28, such" rollers being journaled'in the upper part of. the'cabinet structure.

The bed has a suitable pad 29. This pad has a longitudinal slot 30 below which is, a tension screw 31, this screwhaving ancrank- 32 at the .37 with two clamping jaws 38, these being ar-v ranged to clamp a portion of the patients body on the bed in the same manner as in my previous application.

The mechanism for reciprocating the bed utilizes a rack 39 secured on the under side of the bed below the body clamp 36. Meshing with this there is a segmental gear 40 which is mounted on an oscillating arm 41, this being pivoted at 42 with a frame structure 43 built into the cabinet. This oscillating arm has a series of perforations 44 for adjustment, and connected in one of these there is a link 45, this arm being connected to a lever 45 which is firmly connected to the rock shaft 19. Therefore, on rocking movement of this rock shaft the oscillating arm 41 is actuated in a vertical plane and, hence, reciprocates the bed 26, and this rock shaft is rocked by the oscillating arm 13 having the extension 20. It will, therefore, be seen that as this latter arm and its extension are oscillated in a circular manner that the table has a reciprocating motion.

The degree of the circular oscillating motion of the arm 20 is regulated in the same manner as in my prior application in which it may be seen that this may be from a small oscillation to a large oscillation, and as the oscillation increases in extent, manifestly, the rock arm 19 has a greater degree of rocking motion and this, through the medium of the segmental gear 40, reciprocates the bed varying degrees. In addition, when desired, the link 45 may be adjusted on the arm 41 to give a greater or a less relative motion of the bed and the oscillating arm 20.

The oscillating arm 20 is counterbalanced by means of having a counterbalance arm 4'7 which is secured to the rock shaft 19, this having a counterbalance weight 48 on the end. Thus, in the circular oscillating movement, the counterweight arm and the counterweight only have a vertical oscillating movement. In this construction I place the counterweight above the arm 13.

Another feature of this design over my former application is that end 49 may be substantially closed except for the relatively small opening 50. at the top to allow passage of the lever 46 and the link 45.

The manner of using my body treating table is substantially as follows:

Presuming that the hips and the legs of the patient are to be given the oscillating treatment,

the patient lies on the table so that the body clamp 36 may be clamped at substantially the hips. attached to the tension bracket 25. The hands are also engaged in a holding device, which latter is secured to the tension post 34. Both the tension bracket 25 and the tension post 34 may be adjusted longitudinally of the arm and of the bed, respectively, and, hence, increase or decrease the pull or tension on the body of the patient, and as the pad 37 with the whole of the table top reciprocates this prevents an undue strain being brought on any part of the body. The machine is arranged, manifestly, so that the patient may have the feet clamped to the tension post appended claims.
